One of the many ways you can solve a quadratic equation is by factoring it. You may back-substitute these values of x to the original equation to verify if they are true answers. In this example a equals 2 b is 5 and c is 12 so.
X-1 x30 x 1x 3 0.
Rewrite 7x with 6 x and 1 x. Solving Quadratic Equations by Factoring The general form of a quadratic equation is ax 2 bx c 0 where x is the variable and a b c are constants. In order to solve the quadratic equation ax 2 bx c 0 by factorization the following steps are used. The answers are x - 7 and x 2.
